I think this is a good suggestion. I would support it, but let's give it a few days to garner support in meta.
I would propose that we follow the convention that StackOverflow has taken like you suggested:
create unity-container tag just like SO's.
Audit the current unity questions again to ensure that no unity3d posts remain.
merge all remaining posts in ...
If we look at Stack Overflow, to see the state of their tags.
Portable code can be run with little to no modification in multiple environments. Portable applications can be run from e.g. a USB drive without modifying a computer's environment.

The problem of Language Lifecycles is one that tags are not made to solve.
Tags should categorize questions into clean-cut areas to improve searchability of said questions. The version of a language is (for that categorization) irrelevant.
Special constraints should be explicitly mentioned in the question body.
Continuing your example that means, anybody ...
I agree with this, and it should be done. I started the process by creating the raku tag, but then ran out of privileges to complete it (I don't have enough perl6 tag-rep to complete the synonym.
The tag should be created raku and then existing perl6 questions should be merged in to raku, and then perl6 should be synonym-linked to raku. This will likely ...
Introduce the tag constant-expression
As addressed in the proposal, C++ constexpr functions are a very different concept compared to constants, so this warrants a new tag to describe this style of programming, especially considering how different one has to implement those functions.
Having the compiler execute expressions at compile time is ...
Tag synonyms are, from my perspective, one of the most useful features on Stack Exchange that are the least used and understood.
We don't manage the lifecycle of synonyms, we just create them, and lots of them.
Synonyms are placeholders that:
prevent new tags from being created with that name
are signposts for searching, sorting, etc.
The java-8 ...
I don't think this solves anything.
Maybe I'm different to most as I normally pick well know categories and groups. Think [math] rather than [binomial expansion].
There's not many easing questions. (I had to add a second search term because it comes back with "ease" otherwise which isn't what we're searching for.)
Most of the questions seem to be ...
Stack Overflow has specific tags for individual libraries because users are interested in solving problems using a particular library.
Code Review, on the other hand, is more interested in finding the best approach for accomplishing a task. An answer might even advise you to use a better library altogether. Therefore, we tend to create tags for frameworks ...
So here's what I did to perform the merge requested in the meta-post you linked:
Synonymize python-2.6 into python-2.x
Rename python-2.7 into python-2.x (I botched that one)
Synonymize python2.6 into python-2.x
Synonymize python2.7 into python-2.x
Synonymize python2.x into python-2.x

I guess that the root cause of this issue ...
I primarily performed the synonymization because crypto++ seemed more of a "low-traffic" tag while burnination didn't quite seem appropriate. This may not have been a good move anyway, but I'll let the community decide on it.
Other than that, yes, you can always remove the notification if you'd like.
